Expansion joints are required in structures to allow for movement caused by temperature changes, settlement, or seismic activity. They are typically placed at regular intervals along a structure to prevent cracking and damage.
Construction joints are used to separate different pours of concrete or other materials in a structure. They are typically planned joints that are placed at specific locations to control cracking and ensure proper bonding between different sections of a structure.

Expansion Joints
- Function: To allow for thermal expansion and contraction of building materials, preventing cracking and other damage.
- Types:
- Flexible: Made of elastic materials such as rubber or neoprene, designed to seal and allow for movement.
- Metal: Made of stainless steel, aluminum, or bronze, typically used for larger movements.
- Perimeter: Installed around the perimeter of the building to separate it from adjacent structures.
- Location:
- At intervals determined by material type, anticipated temperature changes, and building design.
- Typically installed in locations where there are changes in building materials, such as between concrete and masonry.
- Located to minimize movement stresses on building elements.
- Size and Spacing:
- Determined by code requirements, building dimensions, and anticipated movements.
- Typically spaced at intervals of 20 to 100 feet.
- Widths vary depending on the anticipated movement and the type of joint used.
Construction Joints
- Function: To separate different phases or portions of a structure, allowing for shrinkage, settlement, and other movement.
- Types:
- Vertical: Used to separate different sections of a wall or column.
- Horizontal: Used to separate different lifts of concrete or masonry.
- Location:
- Vertical joints are placed at regular intervals, typically at the end of each day's pour.
- Horizontal joints are located at the top of each lift of concrete or masonry.
- Treatment:
- Joints are treated to provide a watertight seal and prevent the transmission of loads between adjacent sections.
- Methods include using waterstops, backer rods, and sealant.
- Requirements:
- Joints should be designed to accommodate the anticipated movement of the building.
- Joints should be properly sealed to prevent moisture penetration and structural damage.
- Joints should be monitored and maintained regularly to ensure their effectiveness.
